Intense Light Treatment of Inkjet‐Printed Metal Oxide Hole Injection Layer for Quantum Dot Light‐Emitting Diodes

Journal of the Society for Information Display, EarlyView.
An intense pulsed light (IPL) process enables low‐temperature activation of inkjet‐printed MoOX hole injection layers while preserving the hydrophobicity of pixel defining layers (PDLs). This approach overcomes process incompatibility in multilayer inkjet‐printed QLEDs, achieving uniform thin‐film morphology and stable pixel patterning.

Synthesis of Core–Shell Te@Se Quantum Dots and Their Broadband Photodetector Performance in Low Concentration Electrolytes

Laser &Photonics Reviews, EarlyView.
Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

Single‐Particle Insights Into the Electronic Structure and Enhanced Stability of CsPbBr3/FAPbBr3 Core/Crown Nanoplatelets at the Nanometer Scale

Small, EarlyView.
Single‐particle‐level investigation using scanning tunneling spectroscopy reveals electronic structure and type‐I band alignment of individual CsPbBr3@FAPbBr3 core‐crown nanoplatelet. Crown passivation suppresses deep trap states by 47% and markedly improves electrical stability under repeated bias sweeps.

Synthesis of CdSe and CdSe/TiO2 nanoparticles under multibubble sonoluminescence condition

Ultrasonics Sonochemistry, 2012
CdSe and CdSe/TiO(2) nanoparticles were synthesized under multibubble sonoluminescence (MBSL) condition. The influences of TiO(2) introduced as the sensitizer on the morphology and crystal transformation were investigated. The morphology, phase and optical properties of the final products have been characterized by X-ray powder diffraction ...

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure

Small, EarlyView.
In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.
